On 10 July 1995, following a period of approximately six weeks dry hot weather with minimal rainfall, a number of localised thunderstorms over Birmingham and the Black country caused large volumes of contaminated surface run off to enter the River Tame. There followed a rapid reduction in dissolved oxygen levels in the River Tame which resulted in thousands of fish deaths, with the stock mortality of the Tame estimated at over 95%. The Trent fishery was also affected as far as Burton on Trent. Only extensive remedial actions involving direct oxygen injection, the cessation of water abstractions and the usfe of three cooling towers to aerate water, prevented further downstream fish mortality. This incident, along with others in the Region, has highlighted the need for an emergency response method which can oxygenate large volumes of deoxygenated river water. Following an earlier trial using Hydrogen Peroxide on the River Avon at Finham STW, this trial was instigated on the River Tame. The aims of this report are to: Describe the dosing and monitoring methods used in the trial; Record and interpret the water quality data obtained; Identify possible improvements to the dosing and monitoring regimes used in this trial; Produce recommendations for further investigatory work, and where appropriate future investment and emergency response systems.
